PCT No. PCT/FR96/01778 Sec. 371 Date Jul. 14, 1997 Sec. 102(e) Date Jul. 14, 1997 PCT Filed Nov. 12, 1996 PCT Pub. No. WO97/18485 PCT Pub. Date May 22, 1997This invention relates to a global system dedicated to radionavigation and radiopositioning and includes: a land segment comprising: a global network of ground beacons (RBS) emitting an upwards wide spectrum radioelectric signal to user satellites, a mission and control center (CMC) which creates work plans for some user satellites and transmits them when they fly over the master beacons, a processing center (CT) that receives remote measures sorted by the mission and control center (CMC), separates remote measurements into remote measurements necessary for processing specific to the processing center (CT), and remote measurements specific to some clients of services offered by the said system; a space segment composed of mater satellites (SM) participating closely in operation of the system and client satellites; a user segment composed of client beacons and fixed or mobile client receivers.
